i am so depressed right now. my z car has lost a ton of power. when it idles, it is a really rough idle. and when i accelerate, it sounds like a thumping noise in my exhaust. it sounds like all fuel injectors are working (can tell by the clicking noise). i am thinking it might be the catalytic converter, what do you guys think it is? it hurts me so bad hearing her like this. thanx.
